Wireless sensing network based study type double-radio-frequency interface remote-control device and application thereof

Abstract

The invention discloses a wireless sensing network based study type double-radio-frequency interface remote-control device and application thereof. The wireless sensing network based study type double-radio-frequency interface remote-control device comprises a key module, a radio-frequency receiving module, a radio-frequency transmitting module, a wireless sensing network module, an access sensing network, a control unit, a power source module and a display module. The key module is used for selecting work modes, the radio-frequency receiving module is used for demodulating received 315Mhz radio-frequency signals and transmitting pulse carried with encoding information to the control unit for decoding study process, the radio-frequency transmitting module is used for modulating pulse signals carried with the encoding information and output by the control unit in an OOK (on-off keying) manner and transmitting the same through 315Mhz carrier waves, the wireless sensing network module is connected into the sensing network, receiving and analyzing control commands transmitted by a control terminal through the wireless sensing network, the control unit is used for controlling encoding and decoding, controlling the key module and the display module, coordinating running of the integral system and controlling the power consumption thereof, the power source module supplies power to the remote-control device, and the display module displays relative information. Accordingly, a universal and compatible 315 MHz remote-control device is provided.

Description

technical field [0001] The invention relates to the application field of wireless sensor networks, in particular to a learning-type dual-radio frequency interface remote control device based on a wireless sensor network for learning 315Mhz remote controllers and controlling 315Mhz remote control equipment using wireless radio frequency technology and its application. Background technique [0002] Wireless sensor network integrates sensor technology, embedded computer technology, distributed information processing technology, communication technology, etc., and can collaboratively monitor, sense, collect, and process various environmental or monitoring object information in the network coverage area in real time, so as to obtain Authentic, detailed and accurate physical information data to establish connections between people and things, and between things. Wireless sensor networks are suitable for short distance, low power consumption and low transmission rate, as well as pe...

AI Technical Summary

Problems solved by technology

[0006] Most of the current remote control devices have been set with fixed factory settings when they leave the factory. Different household appliances often need to be controlled by different types of remote controls. Any device with a 315Mhz remote control function must be equipped with a dedicated 315Mhz remote control. Universality of the remote is next to impossible

The 315Mhz remote control devices work independently of each other, and cannot form an intelligent network for collaborative work and linkage, which limits the development of smart homes
